Wonder if this is at all relevant to EEStor's recent work?
Makes sense to use quantum effects, IIRC conventional lead acid batteries work well because the outer electrons of the Pb ions move close to the speed of light. If gold wasn't so ridiculously expensive then this would be an ideal electrode host for Mg-ion or Li-ion cells and eliminate the troublesome copper shunt problem entirely.

As far as being practical goes, this will end up probably being only used for space applications because to make a 100Ah at 48V would probably cost about $750K. On the flip side it could reduce the amount of 238Pu needed which would be a bonus for long duration missions and reduce the risk on launch to safer levels.

i was hoping for 20V at 60Ah for 20k USD...
fuel cells or batteries of this tech would revolutionize the RC hobby market, tablets and cellphones too. i know there are micro fuelcells in development now.

Suppose it were possible to integrate a battery into the airframe, so that what you had was a battery that flies, rather than a flying machine with a battery compartment containing a penalty battery payload.
Other parts of the airframe could be made of organic solar cells - not cells bolted to something - but the cells themselves being airframe - to provide additional power. Organic paper solar cells could perhaps be laminated with resins to produce something very strong and light that produced electricity.

we try to integrate tanks or batteries into the airframe in the way you describe, but they puff and burst in crashes, perhaps i should in the short term just maximize the battery mass.
the NASA operated, Aerovironment produced "Helios" followed the example you illustrate Proud Mary.
